Description

Remove the water treatment method of iron, manganese, arsenic in the underground water synchronously
Technical field
The present invention relates to a kind of water treatment method.
Background technology
So far, sick lesion of the drinking water type ground arsenic that China has found or high-As area are distributed in 13 provinces and regions, are respectively Xinjiang, Shanxi, the Inner Mongol, Ningxia, Qinghai, Anhui, Beijing, Shandong, Sichuan, Jilin, Heilungkiang, Henan and Taiwan.According to new " drinking water sanitary standard " (GB5749-2006), the population that Drinking Water in China surpasses this standard reaches 1,500 ten thousand, and the tap water arsenic content is too high to have become serious public health problem.
Underground water is one of important Freshwater resources of China, and certain areas underground water is unique resource of water supply.In underground water, because contacting with air, the water in the aqueous stratum lacks, behind the oxygen depletion, underground water usually is reducing environment, under this environment, Fe often occurs 2+, Mn 2+Be present in the underground water Fe jointly 2+Existence can promote As under anaerobic environment, transfer in the water.So Fe 2+, Mn 2+, As usually coexists as in the underground water.
Use existing method to handle the Fe in the underground water 2+, Mn 2+With the As complex process, some need add a large amount of chemical agents, and cost is high, and effluent quality is unstable, and can in production practice, be difficult to use with other by product.Seek one simply, effectively, Fe in the economically viable processing underground water 2+, Mn 2+Particularly important with the method for As.
Summary of the invention
The present invention is in order to solve Fe in the existing processing underground water 2+, Mn 2+With the As complex process, cost is high, and the unsettled technical problem of effluent quality provides the water treatment method of iron, manganese, arsenic in a kind of synchronous removal underground water.
The water treatment method of removing iron, manganese, arsenic in the underground water synchronously is following:
One, former water is passed through drop water aeration system 1, the dissolved oxygen to drop water aeration system 1 is 6~8mg/L, water outlet;
